MACHINE FOR PREPARING WELTS.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed September 27, 1912. Serial No. 722,570.

ing at Dorchester, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machinesfor Preparing Nelts', and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for preparing welts and more particularly to machines for rooving and beveling a welt strip preparatory to its use in a welt sewing machine.

One object of the present invention is to produce a welt grooving and beveling ma-. chine which is capable of grooving and beveling the entire length of the welt strip.

Another object of the present invention is to provide improved means for reeling the welt after it has been operated upon by the cutting knives.

Another object of the present invention is to provide the machine with mechanism for automatically stopping the welt reeling mechanism.

Still other objects of the present inven tion are to improve certain details of construction of welt grooving and beveling machines, the advantages of which will be apparent to one skilled in the art, from the following description.

With the above objects in view, the pres ent invention consists in the machine for preparing welts hereinafter described and particularly pointed out in the claims.

In the drawings, which illustrate the pre' ferred embodiment of the present invention, Figure l is a side elevation of the head of the machine; Fig. 2 is a front elevation of the head of the machine; Fig. 3 is a front elevation of the head of the machine, similar to Fig. 2, but showing the parts in a different position; Fig. 4 is a rear elevation of the head of the machine; Fig. 5 is a detail view of the belt shipper lock; Fig. 6 is a detail view showing a plan of the work table; Fig. 7 is a detail of a section taken along the line 7-7 of Fig. 2; Fig. 8 is a detail showing part of the mechanism for rocking the grooving knife carrier; Fig. 9 is a detail view of the mechanism for oscillating the welt guide arm; Fig. 10 is a front view of the presser foot and its carrier detached; and Fig. 11 is a side view of the presser foot and its carrier detached.

Referring to the drawings, the welt strip 2 is fed through the machine by means of feed rolls 4 and 6 respectively, and is drawn over a worktable 8 where it is operated upon by grooving knives 10 and 12 respectively for cutting a stitch receiving groove, and by a two-edged beveling knife 14 for beveling the edge 'of the welt which lies against the upper when the welt is sewed onto a lasted shoe. The carrier which holds the grooving knives 10 and 12 is arranged to be rocked, so that the knife 10 is posi tioned to groove the welt when the welt is drawn forward across the work table by means of the feed rolls 4: and 6, and the knife 12 is positioned to groove the welt when it is dragged backward across the work table by hand. The beveling knife 14 has two oppositely directed cutting edges which bevel the welt when it is drawn either forward or backward across the work table.

The work table 8 is formed by a flattopped steel plate or block which is rigidly mounted on a bracket 16 which in turn is rigidly mounted on the machine frame by means of the screws 18. The middle of the work table is cut away on its under side to receive the beveling knife 14: which is upa wardly and rearwardly inclined and projects through a hole 20 in the rear of the top surface of the work table 8. The beveling knife 14: consists of a substantially triangu lar blade portion which projects through the hole 20 and a shank 22 of a substantially rectangular cross section. ihe shank 22 is slotted at 24: to receive a screw 26 which clamps the knife on an angularly adjusttable knife carrier 28. The knife carrier 28 has a curved rib 30, shown in dotted lines in Fig. 7, which is received in a slot in a vertically adjustable plate 32. The rib 30 and its receiving slot are struck about a center which is approximately the point of intersection of the cutting edges of the knife 1% with the top of the work table 8. The knife can, therefore, be angularly adjusted to change the angle of bevel of the welt without changing the depth of the bevel cut. The plate 32 is splined to the bracket 16 to hold it in vertical alinement and is vertically adjusted by means of a screw 34 in the side of the plate 32 (see Fig. 3). A

v clamping screw 38 received through a 7' curved slot in the knife carrier 28 (being screwed into a threaded hole in the plate 32) holds theseparts firmly. in adjustedfposition. A A deflector or a guard plate AA guides the chip cut by the ibevelingkni'fe .7

downward and prevents itfrom getting into the machine so that'it falls freely out from the bottomof' the, work table;

The" backwardly and forwardly directed grooving kniveslO and 12 respectively are of a substantially J-shaped', cross section, and

v blocks '50. The knives 10' and 12vare longitudinally adjustable so that they'maybe moved down astheir cutting edges; are ground away by sharpening The' knife; carrier 46 is arranged tobe, rocked slightly to bring the backwardly I directed grooving 'fknife l0.

The U-shaped mounted ona substantially ,yokeeshapedsupto be rockedon -the stud 40- porting block 52, which, turn, is mounted "upon .a' rocking supporting frame 54. V The rocking supporting-frame 5.4 is provided with a stud 56 journaled in a bearing 58 in the bracket 16, and the. frame 5.4is. arranged which will be hereinafter described; ,The yoke-shaped supporting block 52' may, for conve'nience,-be designatedas the pre'sser foot carrier because upon it ismounted the presser foot 60.; The presser foot carrier 52 is supported by the rocking supporting memberfii being mounted thereon'by. means of a rod 62 A which is slidinglyflheld in the rocking frame V 54;. The-rod162 passesthroughthe presser foot carrier'52vand is rigidly held therein by apin 64:. I A helical compression spring 66', surrounding theirod 62' and adjusted by the 7 nuts 68, normally holds the presser foot carrier 52 againstthe top of. the rocking frame 5%, butpallows. the Presser foot carrier 52 and knife carrier 46 to be lifted, from the rock ing' frame 54; against the tension of the spring'66. Aoylindricalblock 70 is loosely mountedlin the presser foot carrier 52'. The 1 7 rear face o-f-the block 70 is plain; and fits against the inner. face of the rear leg 72 of the U-shaped knife carrier 46. The front face of the cylindrical block 7 0 is, provided with a tongue 74: which engages a groove in the inner face of' the front leg 76 of the i, knife carrien46, so that the knife carrier are each clamped in'place onthejfront' of V the knifecarrier 46. by means ofjclarnping'v 48 held inplace by clampingscrews ward-1y andbackwardly relatively .tojthe;

The presserfoot 60 is-an elongated platef. of,v substantially the'sameilength as theworktable 8., The under surface of the presser" r foot which lies over the work table hasit two halves. inclinedto each 'otherat very obtuse angle, as shown-in, Figs; 2, 3 andf ll}; so that when the knife carrier'is rocked t depress: the, grooving lmife l0,;the under face. of the presser foot adjacent the groo'v ing knife 10: parallel withthe top" of: the] worktable 8, and sothat'when the grooving knife 12 is depressed the underface 'ofthe presser footadjacent the grooving knife 10 is parallel with the topof the'wor'k table' 8. The presser foot over the, top of the work table iscut away at two places; '98 and so. that the groovingv knives 10 and {12 jplI'O- i ject. through and below, the bottom of the 1 presser foot. The presser foot at 'the 'rearof the work supportingsurface of the work table 8 has :a downward projection 1 043 tFigsI work table and holds thepresser .footi 6 with its carrier 52 and the knife carrier 46 from turning about the rod 62 and so holds the presser foot 60 and the grooving knives 10 and 12 in alinement with the work table. The presser foot 60 is rigidly mounted upon the presser foot carrier 52 by screws connecting the rearward extension 106 (Figs. 1 and 11) of the presser foot to the bottom of the presser foot carrier 52. It will be noted that the knife carrier 46 and the grooving knives 10 and 12 are adjustable relatively to the presser foot 60 and its carrier 52 by means of the adjusting screw so'that a fine adjustment of the grooving knives relative to the presser foot may be had to accurately position the stitch receiving groove in the welt.

The presser foot 60 acts as a top gage to hold the welt firmly against the top of the work table 8 and the downward extension 104 at the rear of the presser foot forms a back edge or side gage for the rear edge of the welt. To position the welt on the work table, two edge or side gages 108 and 110 are provided which bear against the front edge of the welt to hold it snugly against the rear edge gage formed by the downwardly extending flange 104 of the presser foot. The edge gages 108 and 110 are thin metal plates which slide over the top of the work table 8. The parts 112 of the edge gages which come under the presser foot are made thinner, so that a thin welt may be operated upon, leaving two portions 114 of the full thickness under the cut-away portions 98 and of the presser foot. The edge gages 108 and are mounted on blocks 116 and 118 respectively. The blocks 116 and 118 are mounted on the front ends of the sliding bars 120 and 122 which are slidingly mounted in the bracket 16 and are drawn rearwardly by means of helical springs 124 and 126 to hold the edge gages 108 and 110 against the welt. Adjustable stop screws 128 and 130 are threaded through the blocks 116 and 118 respectively and bear against the front of the work table 8 to limit the backward movement of the edge gages 108 and 110 over the work table. The stop screws 128 and 130 are preferably adjusted so that the distance between the rear edge gage 104 on the presser foot and the edge gages 108 and 110 will be the width of the welt which is being operated upon. It will be noted that the edge gages 108 and 110 are separately mounted. In case an irregular enlargement in the welt strip is drawn over the work table, the two edge gages 108 and 110 will yield more easily independently of each other and with less binding of the slide rods 120 and 122 than would a single edge gage of the combined length of the two edge gages.

in order to lift the presser foot 60 and move the edge gages 108 and 110 forward so that a welt may be placed upon the work table in the position to be operated upon by the grooving and beveling knives, treadle operated lever arms 132 and 134 are provided which are arranged to reciprocate the sliding bar 62 and the sliding bars 120 and 122 respectively. The arm 132 contacts with the head of an adjustable screw 136 in the bottom of the sliding bar 62 and raises the presser foot and the grooving knives against the tension of the spring 66. The screw 136 may be turned to vary the amount the arm 132 lifts the presser foot and is locked in adjusted position by means of a lock-nut 138. The arm 132 is formed on a lever 140 which has a number of other arms and which is clamped by means of a clamping bolt 142 on the end of a shaft 144 which is journaled in the machine frame. The lever 140 is turned to raise the arm .132 by means of aconnecting rod 146 connected to an arm 148 on the lever 140 and arranged to be drawn downwardly by means of a treadle (not shown) at the base of the machine. A helical spring 150 connected between the arm 152 on the lever 140 and a stud 154 holds the connecting rod 146 elevated and the arm 132 depressed.

The lever arm 134 has a cross bar 156 at its free end which contacts with both of the slide rods 120 and 122 when the lever arm 134 is turned to the left, as viewed in Fig. 1. The lever arm 134 is journaled on a stud 158 fixed on the machine frame and is turned to bear against the slide bars 120 and 122 by means of a link 160 which forms the connection between an arm 162, integral with the lever arm 134, and a stud 164 which is mounted in the end of the'arm 148 and to which the connecting rod 146 is attached so that when the connecting rod 146' is depressed, the lever 134 is turned to the left, as viewed in Fig. 1. The free ends of the lever arms 132 and 134 are relatively spaced from the slide bars 62 and 120 and 122 respectively, so that when the connecting rod 146 is depressed by the treadle, the lever 132 will engage the slide rod 62 and raise the presser foot 60 and grooving knives before the lever 134 engages the slide bars 120 and 122 to move the edge gages 108 and 110 forward. Conversely, when the treadle is released, the springs 124 and 126 will position the edge gages before the spring 66 is released to draw the presser foot down.

Consequently, the welt will be positioned laterally on the work table before it is engaged by the presser foot. Since the presser foot clamps the work against the top of the work table, it is obvious that it is of advantage to position the welt laterally before the presser foot engages it to hold it down upon the table.

In order to rock the knife carrier 46 to alternately lower the grooving knives 10 backward extension to which is secured by mounted upon the shaft 144.

and 12 in position to, groove the welt, the rocking frame 54 has at its lower end a means of bolts 167 a substantially laterally I V v slidingly mounted a slide 1 block 168. The slide block 168 is'mounted upon an eccentric U-shaped 170 which is formed on the rear end'of a sleeve 172 which is mounted to rotate on the rear end of the shaft 144 which is supported in the machine frame. 7 pinned to the end of the shaft 144 to hold the eccentric sleeve 172in place.- On' the forward end o'f the sleeve 172 are'formed two ratchet teeth 176 which are arranged to be engaged by a rotating pawl 17 8 to turn the sleeve 17 2 and eccentric 17 O-through an rocking the angle of 180 thus alternately frame 54 to the right and left. The pawl 17 8 is pivotally mounted by means of a pin 180-to a pawl carrier 182 which is compression spring 184 holds the pawl 17 8 against the sleeve 172. .In order to rotate the pawl carrier 182, gear teeth 186 are formed on the pawl carrier which mesh with the-teeth of a segmental gear 188 formed on the end of a rocking arm 190, so'th'at when the rocking arm is lifted the. pawl carrier 182 is rotated to the right, as viewed in Fig. 8,"through an angle of a little over 180, the pawl 178 engages one of the ratchet teeth, 17 6 and turns the sleeve'172 through an angle of 180, thus rocking the knife carrier 46. The initial position of the pawl 17 8 is a little behind the ratchet teeth 176, so that the engagement of thepawl and ratchet teeth will always be assured. Consequently, the pawl carrier .182'must be ro tated through an angle of 180 plus the small angular distance necessary to bring the treadle. the arm 152 bring the grooving knives 10 and 12 into;

The welt 2 as'itcomes fromjthe feedgrqlls 4 and 6 is woundona, reel .244. ;Thej ree 244is a sleeveof slightly conical shape mounted j on the forward end of V a friction ally drivenshaft 246 An 'eccentricsleeve 248'is mounted just at the rear of "the; reel tion plate 252,

peripheral slot and has a finger 250 extending over the reel so that the sleeve 248 may be turned to clamp the end of the welt between the reel 244 and the finger 250, as shown in Fig. 3. hen the rotation of the welt reel 244 is stopped by the stop finger 270, the momentum of the welt roll tends to carry it forward and to move the finger 250 of the eccentric sleeve 248 with it and so to loosen the grip of the finger 250 on the end of the welt strip. It is found that the momentum of the welt roll is hardly sufficient to disengage the finger 250 from the end of the welt and the operator has to turn the eccentric sleeve a little to disengage the end of the welt. However, the action of the momentum of the welt roll is to loosen rather than tighten the grip of the finger 256 on the welt.

()n the rear of the shaft is splined a'friction plate 252 which is pressed by means of a spring254 against the side of a pulley 256 which is loosely mounted on the shaft 246 and which is continuously driven when the machine is running by means of a belt 258 running over a pulley 260 on the driving shaft of the machine. A belt tightener 262 is provided to keep the belt under tension. A leather the friction plate 252. The pulley 256 is arranged to be driven more rapidly than the normal rotation of the shaft 247 so that the pulley 256 turns relatively to the fricand the shaft 246 is driven by the frictional drag between the pulley and the friction plate. Thus the shaft 246. and the reel 244 are driven so as always to keep a tension on the welt which is being wound and to allow the speed of the reel 244 to decrease as the welt roll increases in size. The pressure with which the spring 254 holds the friction plate 252 against the pulley 256 can be varied by the adjusting nut 255 so that the tension under which the welt is wound on the reel 244 can be varied. The nut 255 is locked in place by the lock-nut 257. The friction plate 252 has a 266 out therein, the rear face 268 of which is beveled. A stop finger 270 is arranged to engage in the slot 266 to stop the rotation of the shaft 246. The stop finger 270 has a beveled surface 272 which, when the stop finger 27 0 is pressed into the slo engages the beveled surface 268 and moves the friction plate 252 out of contact with the pulley 256, so that the shaft is no longer friotionally driven. The friction of the stop finger 27 0 in the slot 266 quickly brakes the shaft 246. In order to stop the welt reel 244 so that the welt holding finger 250 is at the top of the reel in convenient position for the operator to secure the end of the welt. a stop arm 274 is rotatably mounted on the hub 276 of the friction plate 252. A helical spring 278 friction washer 264 is mounted on V connected between a pin 280 on the friction plate 252 and a pin 282 on the arm 274 draws the arm 274 forwardly and normally holds it against a pin 284 on therear face of the friction plate 252. When the reel is to be stopped,-the stop finger 270 is pressed into the slot 266 and frictionally retards the rotation of the reel. The friction of the stop finger 270 in the slot 266 does not ime mediately stop the reel, which continues to turn until the stop arm 274 contacts with a lug 286, which is mounted on the stop fin- I ger 270 and which is moved into the path of the arm 274 when the stop finger 27 0 is pressed into the slot 266. lVhen the stop arm 274 is arrested by the lug 286, the pin 280, which is fast on the friction plate 252, stretches the spring 278, the tension of which opposes the rotation of the reel and quickly brings it to rest. In case the resistance of the spring 278 is insufficient to stop the reel, the reel is positively stopped by the lug 287 on the rear face of the friction plate 252 which contacts with the back of the stop arm 274. The friction of the finger 270 in the slot 266 and the cushioning effect of the spring 278 are such that, while the contact of the lug 287 against the arm 274 positively stops the rotation of the reel, the lug 287 does not strike sufficiently hard to damage the mechanism. The stop arm 274 is so located on the shaft 246 in angular relation to the finger 250 that when the reel is stopped by contact of the stop arm 274 with the lug 286, the welt holding finger 250 is at the top of the reel in position for the operator to readily secure to the reel the end of the next strip of welting which is passed through the machine.

The welt reel 244 is arranged to be stopped whenever a loose end of welt passes from between the feed rolls 4 and 6. The feed rolls 4 and 6 are yieldingly pressed together so that whenever a loose end of welting passes from between them, whether it be the last end of the entire strip of welt or it be the loose end caused by a break in the welt, the feed rolls move together to set into operation mechanism which presses the stop finger 270 into the groove 266, to arrest the rotation of the welt reel 244. This automatically stops the welt reel when the full length of the welt has been run through the machine and also automatically stops the welt reel in case there is break in the welt. In either case, the welt reel is prevented from running free when it is not winding the welt, and the danger and inconvenience of having avlo ose end of the welt fly out from the rotating welt reel, is obviated. In order to operate the stop finger 270 as above described, it is mounted across the end of the rock arm 288. The end of the rock arm 288 is split and is arranged to be clamped by means of a bolt 290 l 294-011 therea'r end of the rock shaft-296.

V be placedbetW'een-thet vo feed r l lsL V a In order to'wind an 'op'en Work'roll ofwelt the face of the growing welt welt roll. The open work roll in which the welt is reeled allows the water in which the welts are soaked before they are sewn to the shoe, to penetrate to every part of the welt rolland to uniformly temper the welt.

The welt guide is mounted on the lower end of thearm 320. This guide comprises a small roll 368 mounted between two larger rolls 370 and 372. The rolls 368, 370 and 372 are mounted on a pin an which is held by means of a clamping screw 37 6 in the lower end of the arm 320 and projects at substantially right angles thereto. The

' rolls 36,8, 370 and 372 areheld in place by a collar 37 8 fastened to the pin by a'clarnping screw 380. The small roll 368 is mounted upon'a portion of the pin 374: which is eccentric to the bearings of the rolls 370 and 372 so that while the periphery of the roll 368 extends almost to the peripheries of the rolls 370 and 372 on the side of the welt guide next the welt reel, the periphery of the roll 368 on the side away from the welt reel is considerably below the peripheries of the rolls 370 and 372 so that the sides of the rolls 370 and 372 form a welt guiding slot.

As illustrated particularly in Fig. 3, it will be noticed that when the welt is being reeled, the tension on the welt between the welt reel and welt guide and between the feed rolls and welt guide draws the arm 820 to the left so that the welt guide hugs the face of the welt roll which is being wound on the reel. The rolls 370 and 372 allow the surface of the welt roll to freely travel under the welt guide. As the welt roll grows, it pushes the arm 320 more and more to the right, the welt guide always lying against roll. Since the welt guide always lies against the face of the welt roll and the guide is reciprocated back and forth longitudinally of the welt roll, a welt roll of substantially the same length or thickness (measured parallel to its axis) throughout will be built up on the reelQ i-e. In other words, the length of the roll at its center will be substantially the #same as at its circumference and the roll will have substantially fiat trasted with the concave ends which a roll of welting would have if it were wound on a reel without flanges by means of a welt guide reciprocated back and forth at a fixed distance from the reel. Moreover, as the welt guide has the same length of travel throughout the winding of the roll and as it lies against the roll, no side flanges need be provided on the reel 2%.

The operation of the machine is as follows2-Affer a welt strip has been operated on and removed as a roll from the reel 2&4, the machine is ready to groove and bevel another welt strip. Since the previously grooved and beveled strip has been drawn forwardly through the machine, the knife ends, as con-:

carrier is in a position so that the grooving knife 10 is depressed. The feed rolls 4 and 6 are together so that the latch 30% is tripped and the stop finger 270 engages the friction plate 2-52. tarting with the machine in this position, the operator depresses the treadle which raises the presser foot 60 and moves the edge gages 108 and 110 forwardly on the welt work table 8. The operator then slips the for vard end of the welt strip sidewiseonto the work table leaving a length about two feet long at the left of the work table as viewed in Figs. 2 and 3. Tue depression of the treadle in raising the presser foot and opening the edge gages rocks the knife carrier so that the forwardly directed grooving knife 12 is depressed into position to groove the welt. Then the treadle released and the presser reengage the welt strip. It will be noted that when the machine is in thi" position, the finger 236 is depressed so that the operator is unable to start the feed rolls. The operator grasps the welt and pulls it backward across the work table by hand. The grooving knife 12 and the forwardly facing edge of the beveling knife 1% groove and bevel the welt strip to its very forward end so that no welt is wasted. After about two feet of the front end of he welt have been grooved and beveled in this manner, the operator again depresses the treadle and slips the grooved and beveled portion of the welt onto the work table leaving suflicient welt at the left of the table to reach through the feed rolls and down to the welt reel. The operator puts this end between the feed. rolls around the welt guiding roller 368 and secures the end on the reel by means of the finger 250. The depression of the treadle turns the eccentric 170 so that the knife carrier is rocked to depress the backwardlv directed grooving knife, 10. The depression of the treadle also draws down the arm 300 allowing the latch 30% under the action of the spring 308 to engage the catch shoulder 310 so that when the treadle is released, the arm 300 is held depressed by the latch 30% and the friction plate 252 is held against the pulley 256. The welt reel rotating mechanisin is, therefore, in position to rotate the welt reel as soon as the power is turned on after the treadle is rel-ea ed. Then the treadle is released the parts assume the position illustrated in Fig. 3. In this posi tion the latch 232- is raised by the finger 236. The operator then draws the belt shipper forward throwing on the power. The feed rolls f and 6 drag the welt across the work table where it is grooved and beveled by means of the knives 10 and 14:. The welt reel 'Z is frictionally driven so that it reels the welt as fast as it is delivered from the feed rolls, the welt being laid criss crossed back and forth on the reel by means of the in. pring 2 ,4, trippi h latch 304 and aHOW i i lathe only parts 'Whichcontinueto run-and EA machinef'orpreparing fivetshaving- Will out asubstantially V shaped i-groove in f ma hif i ofpr p 7 1 are, Ofcourse, oppositely symmetrical, jo f n; f
